It is seven years after their first expedition, but everything has changed. New team members prove tricky to integrate, and a premature influx of miners challenges the planet's ecological balance. As more mysteries of Went are revealed, the social fabric of the isolated travellers unravels. The planet herself may have answers, but every time Huldar speaks with her he comes closer to death.

On a world of ice and secrets – don’t run. Stranded far from home on a world where climate is the ultimate enemy, the Planet Walkers must survive on their wits. Strange creatures, volcanic eruptions and volatile weather make their expedition difficult enough, but one of the team has a secret that can only make things worse. As the Planet Walkers race to fulfill their mission, one team member's discovery leads to a war against time and the elements, but beneath the beauty of this pristine world lurks terror beyond bearing. Where there is danger in emotion and power in voice, will Huldar's song be enough to save those he loves?  Through danger and loss, romance and betrayal, Shackleton's flowing style will keep you enthralled.
